100 hemiplegic patients are divided into two groups: one group is treated with traditional Chinese medicine (TCM) and acupuncture; the other group is treated with TCM, acupuncture and rehabilitation training. After four weeks, there is difference between two groups in MAS and ADL scores before and after treatment. At the same time the latter's effect is better than the former. It proves that rehabilitation research has important effect on hemiplegia rehabilitation.

To investigate the expression of vascular endothelial growth factor(VEGF) and basic fibroblast growth factor(bFGF) in primary transitional cell carcinoma(TCC) of bladder,and to determine their relationship with magnitude of angiogenesis.Both growth factor were assayed using immunohistochemical technique in 62 cases of TCC.The relationship between the expression of VEGF and bFGF in invasive neoplastic tissues and magnitude of angiogenesis were also investigated.The positive expression rates of VEGF and bFGF in neoplastin tissues were 56 5% and 46 8%,respectively.The expression of VEGF and bFGF showed positive relationship with tumor grades,stages,high recurrence, and shorter survival( P

Purpose To evaluate the application of fluorescence in situ hybridization ( FISH) in detection of EWSR1 gene translocation in formalin-fixed paraffin-embedded tissue samples of Ewing family tumor ( EFT) . Methods Four cases of EFT were collected and their clinical pathological features were obsered. Interphase FISH was carried out in paraffin-embedded tissue of EFT cases, using a EWSR1 dual colar break-apart probe. Fifteen cases of other soft tissue tumor were selected as negative control. Results Translocation of EWSR1 was detected in four EFT cases, which may be a adjuvantly diagnositic value for the diagnosis of atypical cases. Conclu-sions FISH may serve as an adjunctive diagnostic tool in problematic cases of EFT, however, FISH results should be interpreted con-cerning clinical pathological features, morphological patterns and immunohistological results.

AIM:To evaluate the effect of curcumin on impaired learning-memory ability and the expression of high mobility group box protein 1 ( HMGB1 ) and c-Jun N-terminal kinase ( JNK ) in a rat model of Alzheimer disease (AD).METHODS:Male Sprague-Dawley rats, weighing 250~270 g, were randomly divided into 4 groups (n=9):blank control group (group A), model group (group B), curcumin treatment group (group C, curcumin injected intraper-itoneally at 100 mg· kg-1· d-1 for 6 consecutive days) and solvent control group (group D).The rats of AD model were induced by injection of ibotenic acid into the nucleus basalis of Meynert ( NBM) bilaterally.All rats were trained in Morris maze to assess the ability of learning and memory .The expression of HMGB1 and JNK in the hippocampus was detected by the methods of immunohistochemistry and Western blotting .RESULTS:Compared with group A , the average escape laten-cy (AEL) in groups B and D were obviously longer (P<0.05), while AEL in group C in the 5th and 6th days were signif-icantly shorter (P<0.05).The releases of HMGB1 in the CA1 and CA3 areas in groups B and D from the nucleus were a-bundant.Compared with groups B and D , HMGB1 in hippocampal CA1 and CA3 areas in group C secreted out of the nu-cleus decreased obviously (P<0.05).No significant difference of the release of HMGB1 between group A and group C was observed (P>0.05).No significant difference in the expression of HMGB1 in the hippocampus among the 4 groups was found (P>0.05).However, compared with groups B and D , the expression of JNK in group C was decreased obvi-ously (P<0.05).CONCLUSION: Curcumin significantly improves the learning and memory ability of AD rats .The probable mechanisms may be related to inhibiting the release of HMGB 1 from the nucleus of hippocampal neurons and de-creasing the expression of JNK in the hippocampus .

Objective To study the relationship between polymorphisms of RET gene and the incidence of Hirschsprung's disease, investigate the haplotypes of RET gene in patients with Hirschsprung's disease, and analyze the characteristics of single nucleotide polymorphisms of RET gene in Zhejiang Han population. Methods Peripheral blood samples were collected from 123 patients with Hirschsprung's disease and 194 healthy children from 2005 to 2007 at Children's Hospital of Zhejiang University. G enomic DNA was extracted from the peripheral blood, and the genotypes were analyzed using polymerase chain reaction and direct sequencing. The frequencies of haplotypes were estimated using the PHASE software. The frequencies of RET alleles of the 194 healthy children were compared with those of other races. The correlation between RET gene and Hirschsprung's disease was analyzed using the chi-square test, and it was expressed in the form of odds ratio and 95% confidence interval.Results Increased risk of Hirschsprung's disease was observed in homozygous genotypes of the RET alleles -5AA, - 1CC, c135AA and c2307GG when compared with other genotypes ( x2 =57. 775, 20.469, 57. 040,38. 869, P ＜ 0. 05 ). Increased risk of Hirschsprung's disease was also observed in RET alleles -5A, - 1 C,c135A, c2307G when compared with other alleles ( x2 = 85.114, 53.117, 77. 005, 70. 161, P ＜0.05). There was no relationship between the frequencies of the alleles and the types of Hirschsprung's disease ( x2= 0.048,0.265, 0. 395, 0.027, P ＞ 0.05 ). The percentage of patients with haplotype ACAG was 75.2%, which was significantly higher than that of 38.7% in healthy children ( x2 = 62. 776, P ＜ 0.05 ). The frequencies of Hirschsprung's disease-associated alleles of RET - 5A, c135A and c2307G in Chinese were significantly higher than thosein the Caucasians or Yorubas (P＜0.05). Conclusions RET -5G＞A, -1A ＞C, c135G＞A and c2307T ＞ G are associated with Hirschsprung's disease and haplotype ACAG is the core one in Zhejiang Han population. There is no relationship between the frequency of allele and the types of Hirschsprung's disease. The frequencies of alleles of RET -5A, c135A and c2307G in Chinese are significantly higher than those in the Caucasians or Yorubas.

Background and purpose: Factor that binds to the inducer of short transcripts of human immuno-deficiency virus-1 (FBI-1) in a variety of malignant tumors showed high expression levels, which may be closely related to tumor proliferation and differentiation, angiogenesis, metastasis, but its relationship with breast cancer has not been fully elucidated. The purpose of this study was to investigate the expression of FBI-1 in breast cancer cells, and to study the effect of FBI-1 gene expression on the proliferation of breast cancer cells and its possible mechanism. Methods:Real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot analysis were applied to detect FBI-1 expression in normal human mammary epithelial cell line MCF-10A and breast cancer cell MCF-7. RNA interference method was used to down-regulate FBI-1 expression in MCF-7 cells. The cell proliferation was measured by CCK-8 kit and colony formation assay. RTFQ-PCR and Western blot were used to detect the expression of FBI-1 and NF-κBp65 in MCF-7 cells before and after the interference of FBI-1 expression. Results: The expression of FBI-1 was higher in breast cancer cells than that in normal human mammary epithelial cells (P<0.05). The effects of FBI-1 down-regulation inhibited proliferation in MCF-7 cells (P<0.05). At the same time, after inhibition of FBI-1, the NF-κBp65 mRNA and protein expression levels were significantly decreased (P<0.05). Conclusion: FBI-1 is highly expressed in breast cancer cells. Down-regulated FBI-1 expression can inhibit the proliferation of breast cancer cells,and its mechanism may be related to the inhibition of NF-κB signaling pathway.

Objective To evaluate one-stage procedure for the treatment of neonatal intermediate and high imperforated anus. Methods Clinical data of 21 neonates with intermediate or high imperforated anus undergoing one-stage surgical procedure were summarized. Results Postoperative complication included mucous overlap and soiling in 1 case, and occasional soiling in 2 cases. No postoperative constipation developed in any case. Conclusions Neonatal one-stage procedure avoids short comings often seen in staged procedures and needs no colostomy, promoting hyperplasia and prolongs sphincter during early stage, preventing secondary megacolon.

Objective To investigate the relationship between monocyte chemoattractant protein-1 (MCP-1) A-2518G single nucleotide polymorphism (SNPs) and susceptibility of epithelial ovarian cancer(EOC) in Chinese Han population of Hunan region.Methods MCP-1 A-2518G SNPs of the EOC were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis in 92 patients with EOC and 38 healthy women as control.Results MCP-1 A-2518G SNPs had AA,AG,and GG genotypes in cancer and control groups.The frequencies of AA,AG,and GG genotypes were not significantly different between cancer and control groups (AA:17.40％ and 15.79％ ; AG:44.56％ and 52.63％ ; and GG:38.04％ and 31.58％ ; P ＞0.05).Multivariate logistic regression analysis showed that there was no significant correlation between MCP-1 A-2518G polymorphism and EOC (P ＞0.05).Conclusions This present study suggested that MCP-1 A-2518G polymorphism should not be related to susceptibility of EOC in the Chinese Han population of Hunan region.

OBJECTIVE:To study absorption characteristics of naringin in situ single-pass intestinal perfusion model of rats. METHODS:UPLC method was established for the content determination of naringin and naringenin in intestinal perfusion samples of rats. The in situ single-pass intestinal perfusion model of rats was adopted to investigate intestinal(duodenum,jejunum,ileum and colon)absorption and metabolic characteristics [apparent permeability coefficient(Peff),absorptivity,metabolic rate] of naringin(10 μ mol/L). RESULTS:The linear range of naringin and naringenin were 1.25-40,1.25-40 μ mol/L(R2=0.999 4, 0.996 6). The detection limit were 0.5,0.4 μ mol/L,and limit of quantitation were all 1.25 μ mol/L. Precision of inter-day and intra-day,recovery and stability in HBSS solution,perfusion fluid of small intestine and colon were all in line with the standard. Peffof naringin in duodenum,jejunum,ileum and colon of rats were(0.28 ± 0.19),(0.71 ± 0.17),(0.30 ± 0.02),(0.59 ± 0.19) (n=6),without statistical significance(P>0.05).Absorptivities were(2.90±2.14)%,(6.38±3.61)%,(3.69±0.56)%,(6.64± 2.12)%(n=6). Naringin could be metabolized to naringenin in 4 intestinal segments of rats,with metabolic rate of(2.98 ± 1.51)%,(2.53 ± 1.31)%,(2.24 ± 1.33)%,(0.70 ± 0.20)%(n=6). The lowest absorptivity and the highest metabolic rate of naringin were occurred in the duodenum,there were statistical significance compared with colon(P<0.05). CONCLUSIONS:Naringin shows poor permeability and poor absorption in the intestinal tract of rats.There was no specific absorption site in the rat' s intestines for naringenin;naringin could be metabolized to naringenin in small intestine and colon,but metabolic rate of naringin in small intestine is higher than in colon.

Objective To study the changes of trans-diaphragmatic pressure (Ptra) and its correlation with esophageal pressure (Peso) through ARDS piglet model.Methods Five piglets were enrolled in the study.Peso,gastric pressure (Pgas) and intra-thoracic pressure (Pint) was monitored through balloon inserted.The data before ARDS serve as control.ARDS was produced in the piglets through saline lavage.The pressure were observed and the Ptra were calculated.The pressure changes and correlation between Ptra and Peso were analyzed as well.Linear regression with the coefficient of determination and t-test were used as appropriate.Significance was assumed for P ＜ 0.05.Results Peso,Pgas and Pint before ARDS were 7.3 ± 1.9,25.5 ± 2.4,- 1.23 ± 0.21 cmH2O,Ptra was 18.2 ± 1.6 cmH2O.While after ARDS,the data were 4.7 ± 1.4,31.1 ± 3.1 and - 1.79 ± 0.28 cmH2O,and Ptra was 26.4 ± 2.1 cmH2 O,and all these changes were obviously ( P ＜ 0.05 ).The correlation between Pint and Peso,Pint and Ptra (A) and Ptra ( B ) were 0.93 ± 0.025,0.88 ± 0.023 and 0.87 ± 0.37 before ARDS.After ARDS,the correlation changed to be 0.82 ±0.21,0.81 ±0.20 and 0.78 ±0.31.Although a bit decreased,the correlation was still positive (P ＜ 0.01 ).Conclusions There existed good correlations between Peso and Ptra as well as between Pint and Peso before or after ARDS.Ptra was increased obviously after ARDS,which could lead to respiratory muscle fatigue.
